KINGSVILLE, Texas - Gas wasn't the only thing in the tank of a Chrysler Sebring pulled over on U.S. Highway 77 in Kingsville on Tuesday.

The South Texas Specialized Crimes and Narcotics Task Force seized $530,020 in cash hidden in the car's gas tank, according to a news release from the agency.

Agents believe the money are drug proceeds that were being taken to Mexico, the release states.

Kalisha Deary, a 29-year-old resident of Taylor, was arrested on suspicion of money laundering and unlawful use of a criminal instrument. Her bail amount was set at $300,000, according to Kleberg County Jail records.
